A closure member (20) is provided comprising an upper part (14), cylindrical body part (30) which sliding fits through the opening (16), and an engagement member (34) on its underside. I...

An article of footwear is disclosed. The article comprises an insole (3) and a sole element (9) secured to the lower surface (11) of the insole (3). The sole element (9) is formed from a material capable of absorbing impact energy. The article is constructed so that the sole element (9) extends through an opening (15) in the insole (3) and projects to or above the upper surface (7) of the insole (3) and forms a load transfer region for transferring load between a foot of a wearer of the footwear...

An opening arrangement including an openable membrane defined by a weakening line. A pulling device is connected to the membrane by a connecting portion made from a flexible material and includes two arms disposed at an angle to one another. Each arm has a center line. A lower arm is connected via a connection to the membrane adjacent the weakening line and at an angle to a plane defined by the weakening line. The center line of each arm defines a plane which extends substantially parallel with ...

A stopper for plugging an opening formed in a panel comprises a flange portion for pressed contact with the surface of the panel and an insertion portion extended downwardly from the lower surface of the flange portion and adapted for insertion into the opening in the panel. The insertion portion is formed in the shape of a boss, provided in the interior thereof with an annular groove which opens into the upper surface of the insertion portion, and gives rise to outer circumferential walls of a ...
